I am making two assumptions from your post:
   You have a modified VW 2.2 engine, not a Subaru 2.2
   That you used smoke to test for vacuum leaks around where the injectors
go into the intake

If the above is true...
  I think that the most likely cause for a flooded condition when
restarting would be a leaking injector dribbling fuel into the intake until
the pressure in the fuel system drops.  I would test for this by pulling
each pair of injectors out of the intake without disconnecting the hoses or
wires and using a container to catch any drips, pressurize the system by
turning the key a couple of times.

If your injectors pass the above test, I would then check the resistance of
temperature sensor 2 at various temperatures.

And of course "check your grounds"   :-)

Good luck,
Larry A.
